The HD Music Center HDM-03 adopts the specialized 32-bit high-performance multimedia processor and DSP solution. The reference clock system is the industrial-class digital phase-locked loop (DPLL) system, which effectively reduces clock jitter in transmission of digital audio signals and achieves an ultra-low Jitter. In addition, by proprietary technology the audio coding and decoding software can process 24Bit/192KHz high bit rate digital master tape audio stream at a high speed and support the decoding of all kinds of digital audio formats (WAV//WMA/ APE/FLAC/ALAC/ACC). In the future, through firmware upgrading, the device can support more audio formats.

The audio D/A decoding part adopt the flagship-level decoding chip - WM8741 with digital filter from Wolfson of theUK. Known as a D/A chip with the best hearing impression, this chip can produce “simulated feel” sounds more natural than those produced with traditional digital simulated converters. What’s more, the reference circuit has been specially optimized and calibrated by engineers from the plant of Wolfson, as well as passing the factory test made by Wolfson. As a result it can provide SNR of 128dB (monophony) which guarantees a high quality of digital audio rendering. Besides, for the reason that standalone CPU is put to control the D/A decoding chip, this device can also be used as a high-performance independent D/A converter (24Bit/192KHz).
